Hard X-Ray Emission from Partially Occulted Solar Flares: RHESSI Observations in Two Solar Cycles
Frederic Effenberger, Fatima Rubio da Costa, Mitsuo Oka +5
Flares close to the solar limb, where the footpoints are occulted, can reveal the spectrum and structure of the coronal loop-top source in X-rays. We aim at studying the properties…
Fine-pitch CdTe detector for hard X-ray imaging and spectroscopy of the Sun with the FOXSI rocket experiment
S. Ishikawa, M. Katsuragawa, S. Watanabe +8
We have developed a fine-pitch hard X-ray (HXR) detector using a cadmium telluride (CdTe) semiconductor for imaging and spectroscopy for the second launch of the Focusing Optics So…
The First Focused Hard X-ray Images of the Sun with NuSTAR
Brian W. Grefenstette, Lindsay Glesener, Säm Krucker +20
We present results from the the first campaign of dedicated solar observations undertaken by the \textit{Nuclear Spectroscopic Telescope ARray} ({\em NuSTAR}) hard X-ray telescope.…
Simulation of Quiet-Sun Hard X-rays Related to Solar Wind Superhalo Electrons
Wen Wang, Linghua Wang, Sam Krucker +1
In this paper, we propose that the accelerated electrons in the quiet Sun could collide with the solar atmosphere to emit Hard X-rays (HXRs) via non-thermal bremsstrahlung, while s…
The first X-ray imaging spectroscopy of quiescent solar active regions with NuSTAR
I. G. Hannah, B. W. Grefenstette, D. M. Smith +15
We present the first observations of quiescent active regions (ARs) using NuSTAR, a focusing hard X-ray telescope capable of studying faint solar emission from high temperature and…
